Horizontal Control in Kansas City by State Plane Coordinates

Kansas City, Mo., has grown through annexation from 60 sq miles in 1940 to 316 sq miles in 1963. This growth resulted in a need for a good horizontal control system with permanent field monuments and accurate office data. To obtain satisfactory results from a control system it is necessary to establish all control points very accurately using the most accurate measuring equipment, and mathematical balancing techniques available. Correcting errors and adding data to the system is a problem to sponsor and user, particularly the correction of known errors. The State Plane Coordinate System provides a common base for control. When properly utilized, the system provides a means of describing property control points, and is the basis for relocating those points in the field when required.
